Costa Rica from the US: what to expect

Costa Rica is closer and easier than most first-time US visitors expect: 3 hours from Miami, about 6 from Los Angeles, no visa for up to 180 days, US plugs, Central Standard Time and dollars accepted almost everywhere. What takes adjusting is the driving, the rental car insurance and the two lines on every restaurant bill. Checked September 2026.

Which US cities fly nonstop, and how long is the flight?

Most of the big hubs, in less time than crossing the US. San José’s airport (SJO) lists these nonstops on its own connectivity page, as of September 2026: United from Houston, Newark, San Francisco, Denver, Los Angeles and Chicago; American from Miami, Dallas, Charlotte and Chicago; Delta from Atlanta and Los Angeles; JetBlue from Fort Lauderdale and New York; Southwest from Houston, Orlando and Denver; Alaska from Los Angeles; Frontier from Orlando; Avianca from Miami; and Breeze from Tampa starting October 2026. Flight times per FlightsFrom: Miami 3 hours 12 minutes, Dallas 4 hours 16, Chicago 5 hours 19, Newark 5 hours 28, JFK 5 hours 40, Los Angeles 6 hours 7. Liberia (LIR), in Guanacaste, lists 16 US cities, among them Miami, Dallas, New York, Chicago, Los Angeles, Seattle, Boston, Atlanta, Denver and Houston. Many are winter routes: FlightsFrom shows Washington Dulles and Chicago to SJO starting 31 October and Atlanta on 18 December. Fly into SJO for Escazú, Punta Leona, Monteverde and the Caribbean; fly into LIR for Sámara and the rest of Guanacaste.

Do you need a visa, and how long can you stay?

No visa, and up to 180 days. The United States is in Costa Rica’s first entry group, which the tourism board’s entry page says may stay up to 180 calendar days, non-extendable; The Tico Times reported the increase from 90 days in October 2023. The officer writes the number of days on your stamp, so read it, per Costa Rica Vibes (September 2026). Guanacaste Airport’s immigration page lists what to have ready: a passport in good condition, a return or onward ticket, and the address of where you are staying. The airport puts the minimum passport validity for the first group at one day and Costa Rica Vibes recommends a three-month margin; take the margin, because airlines apply their own rules. No vaccines are required from the US; a yellow fever certificate applies only if you arrive from listed countries in South America and Africa, even after a stopover there, per Costa Rica Vibes.

What about customs and the exit tax?

The $29 departure tax is built into most tickets, so there is no line to pay it. Guanacaste Airport’s page says most airlines include it and, if not, you pay $29 per person at the Banco de Costa Rica desk in the lobby; Two Weeks in Costa Rica says the same for SJO (October 2025). The airport asks you to arrive 3 hours before an international departure. On the way in, customs is an X-ray of your bags; the airport says to declare cash of $10,000 or more and that fresh food, plants and seeds without a phytosanitary certificate are prohibited. Returning, the free CBP Mobile Passport Control app takes your declaration on your phone up to 4 hours before landing at most major US airports, for groups of up to 12.

Can you drive there like at home?

Yes, with a different rhythm. Your US license is valid; for how long depends on who you ask. The tourism board’s FAQ says three months, and The Tico Times reported on 30 August 2026 that a reform to Article 91 of the traffic law lets tourists drive for the stay stamped in the passport. Almost everyone navigates with Waze, which Costa Rica Vibes says marks hazards and police checks; use the map pin we send you. Speed limits are in kilometers per hour, gas stations are full service at a regulated price, and the Route 27 tolls take dollars and give change in colones. It gets dark around 18:00 all year, and Two Weeks in Costa Rica’s rule for first-timers is not to drive long distances after dark: faded lines, no lighting, rain and cyclists on the shoulder. Land by early afternoon or sleep near the airport.

The insurance is the trap. Costa Rican law requires liability coverage on every rental, which Costa Rica Vibes (2026) says comes pre-checked and Two Weeks in Costa Rica (February 2025) prices at $15 to $25 a day; no credit card replaces it, and most online booking sites leave it out of the quote, which adds hundreds of dollars at the counter per Two Weeks in Costa Rica. The collision damage waiver is the part you can decline with a printed letter from your card issuer, after which the agency holds $1,000 to $2,500 on the card. Their all-in estimate for a sedan is $500 to $750 a week in high season. None of the three homes below needs a 4x4.

Do they take dollars, and what are the two lines on the bill?

Dollars, yes; the two lines are tax and service. The tourism board says US dollars are widely accepted, and Costa Rica Vibes’ advice is to carry clean $20 bills or smaller, expect change in colones, and pay in colones when you can, since shops set their own rate. On 16 September 2026 the Central Bank’s reference sell rate was 449.49 colones per dollar. Cards work almost everywhere, small restaurants sometimes want cash or a $5 minimum, and ATMs in every town give either currency. On a restaurant bill you will see 13% tax (the tourism board’s figure) and a 10% service charge, which Costa Rica Vibes (September 2026) says is added to every meal, sometimes already inside the menu prices. That 10% is the tip: locals generally leave nothing more, and 5% to 10% in cash for excellent service is generous.

Will your phone work?

Yes, and cheaper than roaming if you plan. Two Weeks in Costa Rica calls coverage good; our houses measure 118 Mbps at Casa Azul, 122 at Casa Almendros and 171 at Alta Pietra. AT&T’s International Day Pass is $12 a day for your home plan’s talk, text and data in 210-plus destinations; whichever carrier you use, confirm Costa Rica is on its list. For a longer trip, land with an eSIM: Airalo’s Costa Rica plans run on the Liberty network and load before you leave, and Kölbi, the state carrier, sells prepaid SIMs and its own eSIM. We work on WhatsApp: send your flight number and we confirm your check-in there.

When should you go, and what feels the same?

December to April on the Pacific, August to October on the Caribbean. Costa Rica Vibes splits the year into a dry season from December to April and a green season from May to November, with rain that usually comes in the afternoon; September and October are the wettest Pacific months and the driest on the Caribbean coast. Guanacaste and the Nicoya Peninsula, where Sámara sits, are hot and dry most of the year with short afternoon storms from May to October; the country runs 75 to 95°F by region. What feels familiar: Central Standard Time year-round with no daylight saving, per timeanddate.com, so Chicago time in winter and one hour behind it in summer; 110 V outlets with US two-prong plugs; tap water the tourism board calls potable in most of the country. What feels different: distances are quoted in hours, and Costa Rica Vibes adds an hour to any Google Maps estimate.

What is cheaper, and what is not?

Rides are cheaper; fuel and parks are not. Uber from the airport to Escazú is 6,000 to 10,000 colones per Route Pura Vida (May 2026), about $13 to $22. Gasoline is regulated and sold by the liter: RECOPE’s price on 11 September 2026 was 726 colones for súper, roughly $6.10 a gallon at the Central Bank rate, with a rise to 764 proposed for October. National parks charge foreigners more and sell tickets only online through SINAC: Manuel Antonio is $18.08 per adult with tax per Two Weeks in Costa Rica (September 2026), closed on Tuesdays. The US State Department rates the country Level 2 (April 2026) and says petty crime is common, so nothing stays visible in a parked car and beach bags stay with someone.

Where to stay

Three of our homes cover the trips US guests take most. Casa Azul in Punta Leona is the beach trip from SJO: a single-story house for eight with a private pool in the middle of the floor plan, a supermarket 75 meters away and the beach about 15 minutes on foot, from $287 a night, about an hour from the airport on paved road, 90 minutes with traffic. Casa Almendros in Sámara is the Guanacaste trip from LIR: a beachfront house for six with three air-conditioned bedrooms and a gate onto the sand, about 2 hours from Liberia, from $303 a night, two-night minimum. Alta Pietra in Escazú is the first or last night: a one-bedroom for up to four with a king bed, a pool, a hot tub and gated parking, 20 to 30 minutes from SJO, from $150 a night, two-night minimum. All three book on Airbnb, and the WhatsApp number next to the button reaches us directly for your flight number, your arrival time and anything this guide did not answer.
